Help and support
Questions about Ferry, a transfer that won't work, or your privacy? Start with the answers below, or write to us.
Tell us your device and system, Ferry's version (Settings → Updates), and what happened. Please don't include share links you want to keep private. Bugs and feature ideas are also welcome as GitHub issues.
The download doesn't start, or stops.
The recipient downloads from the sender's device, so the sender's Ferry must stay open (on a computer, closing the window keeps it running in the tray) and the computer awake. Interrupted downloads resume where they stopped once both are online again.
Why does it say “Via relay”, and is that slower?
When the two networks block a direct connection, an encrypted relay passes the data along. Relays can't read your files, but the free public relays are shared and rate limited. For the best speed through relays, run your own and enter it in Settings → Connections.
Is there a size limit?
No. Ferry sends files from your device, so the only limits are your disks and your connections. The recipient needs room for the files, plus temporary room while they download.
Who can download what I share?
Anyone who has the link, QR code or ticket file, while the share is on. Send links privately, protect ticket files with a password if you like, and use Stop sharing when you're done. Stopping takes effect immediately.
Can my phone send files?
Not yet. Ferry for Android receives: scan a QR code or open a share link, and the files land in Downloads/Ferry. Sending from a phone, and an iPhone app, are planned.
Where are received files on Android?
In Downloads/Ferry, where your Files app and other apps can find them. Each download has Open (or Show) and Share buttons in Ferry.
Do you see my files?
No. Files go from one device to the other, end-to-end encrypted, and nothing passes through a server of ours. The privacy policy lists the services Ferry does talk to.
How do I check that my download of Ferry is genuine?
Every release is built by GitHub Actions from the public source and comes with checksums and a build attestation. For Android, the download page shows the APK's checksum and signing certificate.
